SPECIFICATION forming part of Letters Patent No. 729,221, dated May 26, 1903.

Application filed February 14., 1903.

To all wlwnt it may concern:

Be it known that I, ALONZO E. RHOADES, a citizen of the United States, and a resident of Hopedale, county of IVorcester, State of Massachusetts, have invented an Improvement in Spinning-Spindles, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of simple and efficient means for equalizin g the strain on a spindle-base when the nut is applied thereto to retain it 011 the spindlerail, even when the longitudinal axis of the base is not at right angles thereto.

In order to make the longitudinal axis ofthe spindle vertical, it is often necessary to have the bottom of the spindle-base at an angle to the rail, this presupposing, of course, that the rail is not truly horizontal. This leveling of the spindle-base is usually accomplished by inserting paper, cardboard, or a thin shim under the edge thereof, which must be elevated, and this cants the depending threaded end or shank of the base relatively to the rail so that the latter will not be engaged squarely by the retaining-nut when screwed up on the shank, but will be inclined thereto. hen the nut is set up, the strain is brought upon one side of the casting forming the spindle-base, tending to weaken it and frequently resulting in breakage. By my present invention this inequality of the strain upon the base is avoided, even though the latter is set at quite an inclination relatively to the rail.

The various novel features of my invention will be described hereinafter and particularly pointed out in the claims.

Figure l is a side elevation of a spindle-base and part of a spindle, the base being secured to the rail and with one embodiment of my invention illustrated in use. Fig. 2 is a partial sectional detail showing the slope of the spindle-rail exaggerated, to more clearly indicate the manner in which unequal strain upon the base is obviated; and Fig. 3 is a diametral section of the retaining-nut an d the equalizing-collar, with which it cooperates.

Referring to Fig. .l, the spindle S, broken off to save space; the spindle-base B, enlarged at B to rest upon the spindle-rail R, and having Serial No. 143693. (No model.)

an externally-threaded shank I3 to extend through the rail, may be and are of any wellknown or usual construction.

In Fig. 2 I have shown a shim 3 inserted beneath the enlargement of the base, at one side thereof, to level the spindle-base and bring the longitudinal axis thereof into vertical position, because of the inclination of the spindle-rail R, though paper, cardboard, or any other leveling means, screws, or other means may be employed, all being well known. \Vhen thus leveled, the shank I5 is not at right angles to the rail and the ordinary retaining-nut would, if used, bear at only one side against the rail, and thereby subject the spindle-base to unequal strain. To 0bviate this objection, I make in the end of the retaining-nut n nearer the rail a rounded' socket or concavity, as 0%, and from the nature of the case this socket will be annular and concave in cross-section, as shown in Figs. 2 and 3. An equalizing member (shown as a ring e is adapted to loosely surround the shank of the spindle-base between the rail and the nut, the face 6 of said equalizing member to contact with the rail being fiat, while its opposite face 6 is convexed' or rounded on the same curvature as the socket of the nut. This face 6 will be annular and convex in cross-section, manifestly, and when the nut is set up the convex face of the equalizing member enters and is seated in the socket n of the nut, thus forming a species of ball'and-socket connection or knucklejoint between nut and ring. Even if the base is leveled up so that its longitudinal axis is not at-right angles to the spindle-rail, as shown in Fig. 2, it will be manifest that when the nut is set up the pressure on the base will be equalized through the cooperation of the nut and equalizing member. 011 the other hand, if the latter member be omitted and the usual nut be employed the latter will not rest squarely against the rail, and the strain will be brought on one side of the spindlebase;

,The inclination of the rail is exaggerated in Fig. 2 to more clearly show the operation and effect of my invention.

As the socket in the nntand the convex face of the equalizing member are sections of spheres of like radius, it will be seen that the spindleba'se may be leveled in any direction Without causing unequal strain on the base when the nut is set up.

Having fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. A spindle-base having a threaded shank to extend through the rail, a retaining-nut screwed onto the shank and having an annular socket in its top, and an equalizing-collar having a fiat face to bear against the bottom of the rail and an opposite, annular convex face to fit the socket in the nut.

2; A spindle-base having a threaded shank to extend through the rail, a retaining-nut screwed onto the shank, and having a rounded socket in one end, and an equalizing-collar loosely surrounding the shank between the rail and nut, said collar having a fiat face to bear squarely upon the rail, and an opposite rounded face to enter and fit squarely the socket in the adjacent end of the nut.

3. A spindle-base having a threaded shank to extend through the rail, a retaining-nut adapted to be screwed onto the shank and having a rounded socket in its upper end, and

. an equalizing-collar having a flat face to rest
